Quickwave Software

Hello Nortek,

I use the Seastate Software to measure waves and currents, however i am confused about the settings of  data conversion...

so i am interested in the Quickwave-Software, but I am a little afraid if I really could use or need the programm.

It is possible to send you one example of my  awac-file (*.wpr)  and you will check if  the  created  Quickwave *.wap  file is correct  (i.e header, the default settings for wave-measurements are correctly set,...). I think you have an ftp-server for uploading, is that right?

Thanks and Best regards

Jens

Hi Jens,

Yes we do have an ftp site for uploading data files:

ftp.nortek-as.com/pub/incoming

Please inform us once you have uploaded it.  You can inform us via email inquire@nortek-as.com

As for the Seastate software, can you be a little more specific about which settings are confusing and then I can perhaps provide some guidance steps.

I would also like to hear what your objectives are so that I can suggest the best solution path for software.

kind regards,

Torstein

Hi Torstein,

Our data was collected using a Nortek AWAC unit. This unit was moored in the North Sea (~30m depth).

A cable is used for the connection between the datamanagement unit  and the AWAC (also the power supply is cuducted via this cable).

The data managment software is Seastate. Via a radio link ftp transfer,  we get current raw data, in form of *.wpr files (our Awac is not equipped with NIP so we get the raw data). Every hour we get a  new data transfer and every day we get and create a new file.

In order to bring those raw data into a data base, I have to convert and shape the raw data ( I use matlab). Today i convert the currents data with the awac-ast Software and get ascii data of different parameters (a1, a2, a3 , wad, whd, hdr,...). Read in matlab and....O.K.

Now i try to convert the wave parameters (Hm0, Hs, H10, Hmax, Ts, Dir...) with the Seastate software (export data ; txt; save... or with the configure procedure ) and here I am confused . Mabye you could give some explicit guidlines about wave data conversation with SeaState.

I hope the data is not corrupted....

Nevertheless, i try the Quickwave Demo and the *.wap files looked useable (ascii wave parameters in shape).

Another question:

Include the wap-file the timeseries of the single wave height? I try to find this in the wave parameters extracted the ast software, but can't find them...

Thanks Jens

I have uploaded two data files (jfischer_testdata.zip)

Hello Jens,

I just want to make sure that I fully understand how your system is set up.  For what I read, You have an AWAC deployed with a cable to land where you are running the SeaState software.  SeaState collects the raw data at some location, and from here you are exporting the raw  (*.WPR) data - with some other service/software? - via radio link.   The transfered raw data file is then processed with the AWAC-AST software to get the current data files in ASCII format.

I am a little confused where you get your processed wave parameters from, but I will assume that this is done by the SeaState software and transfered via ftp as well - right?

If you have wave parameters already, I am a little unsure why you need to process the data again in Quickwave, since this will generate the same wave parameters.

For the sake of others following along in this thread, the SeaState software can export ASCII text files of current, waves, and sensor data.  This is set up in the "Configuration Procedure".  Here in the configuration procedure the user is taken through a 7 step configuration where the comms/instrument/processing is configured.  In order to configure wave and current data for export (ftp) in ASCII format the user will have to

(a) enable wave estimates in the "Data Output" tab, with ASCII format.

(b) Next in the "Recording" tab the user would enable data recording with a specified folder.  Furthermore the user will have to check on the "export secondary formats".  Further down the is a list of which processed data is exported and the span of time.

(c) Finally, if the user is using ftp export, the user will have to configure the ftp setting for exporting remotely (as opposed to storing locally on the PC).  Here the user may also export graphic images of the data in addition to enabled ASCII data.

Jens, I am not sure why you are using the AWAC-AST software (or need the QuickWave) software for data conversion if you have the possibility to have this data automatically generated for you with SeaState.  I suspect that there is something that I am misunderstanding, so I hope that you can enlighten me.

I have also downloaded the data and just had a look at it.  The first file shows that the AST beam is likely blocked and the as a result the data will not be that good here; the second file shows that the AST is not blocked and the data looks Very good.

kind regards,

Torstein

Hello Torstein,

Our station with the data managment system is located 40 km offshore. Via the radio link transfer we get data onshore.

Our data is not processed! The awac ist not equipped with the Nortek Internal Processor (NIP)... so we get just the raw data (*wpr). 

-> Just when you activated NIP you can use the "Data Output" tab (but NIP is not installed)

But I think the raw data include all parameters. If I reprocessed the binary  Data (raw  *.wpr Data) at home (with the Seastate software), i can take a look onto the data but to convert the raw data with Seastate is a problem. So i use ast for the currents and i think that i need another programm for wave processing.

I am surprised  why the AST beam does not work or blocked, do you have any idea?

Best regards,

Jens

Hello Jens,

I am aware that we discussed this matter outside of the forum, but for the benefit of others following along I am going to point out the solution for getting processed data transfered.

I see now the problem. The text in the Seastate help is misleading and would suggest that you must have the NIP to output processed data. Sorry for the confusion.

You can output processed results with Seastate. This is done by
1) Enabling data recording in the "Recording" tab.
2) Enabling "exprot secondary formats".
3) Adding the necessary data type ine the "Export formats" table at the bottom of the dialog window. Each field in the table can be modified by clicking on it and selecting the item of interest in the drop down box - click on the arrow to the right.
